An epic fundraising campaign hoping to help a young boy in his second battle with cancer has garnered the attention of one of the world's biggest bands.

None other than The Rolling Stones sent their backing to the #HelpJack movement over the weekend, as 12-year-old Hartley lad Jack Howard continues to receive treatment for kidney cancer at the Children’s Hospital Los Angeles in Sunset Boulevard.

Keith Richards recorded a message from Las Vegas for the Gravesend Grammar School pupil, which has already been viewed almost 50,000 times on social media.

The Dartford rocker said: "Hi Jack - we're all thinking of you, mate. You've gotta keep fighting, you know."

Drummers Ronnie Wood and Charlie Watts were also pictured showing their support, with more than £200,000 so far raised to help Jack's family pay for treatment and accommodation in the States.

Jack enjoyed a personal visit from another famous face last week, as LA Galaxy footballer A.J. DeLaGarza - a former teammate of David Beckham - stopped by the hospital to put a smile on his face.

Plenty of support has also been received from Jack's beloved West Ham United, with co-chairman David Sullivan personally contributing to the total raised.

Almost £160,000 of the total has been raised through the generosity of online donations. If you would like to help, head to crowdfunder.co.uk/jack-howard.
